To answer this question, you'll need to use permutations and factorials.

Factorials are any integer with an ! after it. This means that all of the integers before that number are multiplied together with said number.

This question will use the following formula:

n represents the amount of items in a set, and r represents the amount of items in each combination within the set.

You have 18 students, and you can choose any combination of 3 students. Plug your values into the formula:

There are 4896 different combinations of students that Ms. Lunette can choose.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
